Noun
the number of arguments that a function can take
Source: WordNetConsequently, the number of operands encoded in an instruction may differ from the mathematically necessary number of arguments for a logical or arithmetic operation (the arity ). Source: Internet
If the arity of the operators is fixed, the result is a syntax lacking parentheses or other brackets that can still be parsed without ambiguity. Source: Internet
A more general situation where this trick is possible is with Omega-groups (in the general sense allowing operators with multiple arity). Source: Internet
Examples The term "arity" is rarely employed in everyday usage. Source: Internet
For example, if the domain of discourse consists of integers, a function symbol f of arity 2 can be interpreted as the function that gives the sum of its arguments. Source: Internet
In contrast, partial function application refers to the process of fixing a number of arguments to a function, producing another function of smaller arity. Source: Internet
